I like the name "Quantum Computing", for this SE.
It's sexier than just "Quantum".
So I'm not suggesting to change it.
But that doesn't mean questions have to be only about quantum computing.
In my mind the following are also related enough to be appropriate
- quantum communication
- quantum information
- quantum metrology
- boson sampling (it's not "computing", but it's related)
- quantum annealing
- classical algorithms for quantum simulation (not necessarily of QC)
Most "quantum computing" research groups work in many of the above areas.
When I entered my PhD I was hoping to work on quantum computing, and the group had been working on quantum computing for over a decade, and still was during my interview process, but when I arrived at Oxford, the group had shifted their interest into a new topic that was sexy at the time, called "quantum biology".
We've already had a quantum biology question here: Quantum simulation of environment-assisted quantum walks in photosynthetic energy transfer
And this was actually the first question I answered, on my first day on this SE. I is what got me the reputation to start participating more actively on this SE.
Recently we have had a question of whether or not quantum foundations questions are appropriate:
Is there a way that surreal maths can be used in quantum theory?
Funny enough, I also had wished to pursue quantum computing for my undergraduate thesis and joined Ray Laflamme's group (Director of the Institute for Quantum Computing at the time), but his interest at the time was not in quantum computing but in the "3-slit experiment" which had its heart in quantum foundations.
The "Institute for Quantum Computing" has lots of people working in Quantum Foundations or "Quantum Information" or "Quantum Communication" more than "Quantum Computing". If that can be the case, then why can't we welcome quantum foundations questions here? It gives us more views, more questions, and ultimately, people here are more likely to give a good answer about quantum related things here than on the physics SE. I don't go to the physics SE unless I have a specific question, but I browse here because it's fun.
